CSharp 动态创建控件

一、添加GroupBox控件

1.实例化并显示

csharp //实例化GroupBox控件 GroupBox groubox = new GroupBox(); groubox.Name = "gbDemo"; groubox.Text = "实例"; //设置上和左位置 //groubox.Top = 50; //groubox.Left = 50; //通过坐标设置位置 groubox.Location = new Point(12, 12); //将groubox添加到页面上 this.Controls.Add(groubox);

二、在GroupBox控件中添加TextBox控件

 1.实例化并显示

csharp
//实例化TextBox控件
TextBox txt = new TextBox();
txt.Name = "txtDemo";
txt.Text = "txt实例";
//将TextBox在GroupBox容器中显示
//txt.Parent = groubox;
//将TextBox在GroupBox容器中显示
groubox.Controls.Add(txt);

2.置于顶层和置于底层

csharp //置于顶层 txt.BringToFront();

//置于底层 txt.SendToBack();

3.添加事件



csharp
//添加Click单击事件
txt.Click += new EventHandler(btn_Click);


//定义Click单击事件
private void btn_Click(object sender, EventArgs e)
{
MessageBox.Show("事件添加成功");
}

三、添加多个

1.动态添加多个

csharp //添加控件 public void AddGroupBox() { string name = "gbox"; for (int i = 0; i < 3; i++) { GroupBox gbox = new GroupBox(); gbox.Name = name + i; gbox.Text=name+i; gbox.Width = 300; gbox.Height = 100; gbox.Location = new Point(32, 20 + i 150); this.Controls.Add(gbox); //调用添加文本控件的方法 AddTxt(gbox); } } //添加文本控件 public void AddTxt(GroupBox gb) { string name = "txt"; for (int i = 0; i < 3; i++) { TextBox txt = new TextBox(); txt.Name =gb.Name+ name + i; txt.Text =gb.Name+"|"+ name + i; txt.Location = new Point(12, 15 + i 30); gb.Controls.Add(txt); } }

实例：

csharp
using System;
using System.Collections.Generic;
using System.ComponentModel;
using System.Data;
using System.Drawing;
using System.Linq;
using System.Text;
using System.Windows.Forms;
namespace Select_ListBox 
{
    public partial class Form2 : Form 
    {
        TextBox txt = new TextBox();
        public Form2() 
        {
            InitializeComponent();
        }
        private void Form2_Load(object sender, EventArgs e) 
        {
            AddGroupBox();
            ////实例化GroupBox控件
            //GroupBox groubox = new GroupBox();
            //groubox.Name = "gbDemo";
            //groubox.Text = "实例";
            ////设置上和左位置
            ////groubox.Top = 50;
            ////groubox.Left = 50;
            ////通过坐标设置位置
            //groubox.Location = new Point(12, 12);
            ////将groubox添加到页面上
            //this.Controls.Add(groubox);
            ////实例化TextBox控件
            //TextBox txt = new TextBox();
            //txt.Name = "txtDemo";
            //txt.Text = "txt实例";
            ////将TextBox在GroupBox容器中显示
            ////txt.Parent = groubox;
            ////将TextBox在GroupBox容器中显示
            //groubox.Controls.Add(txt);
            ////置于顶层
            //txt.BringToFront();
            ////置于底层
            //txt.SendToBack();
            ////添加Click单击事件
            //txt.Click += new EventHandler(btn_Click);
        }
        ////定义Click单击事件
        //private void btn_Click(object sender, EventArgs e)
        //{
        //    MessageBox.Show("ss");
        //}
        //添加控件
        public void AddGroupBox() 
        {
            string name = "gbox";
            for (int i = 0; i < 3; i++) 
            {
                GroupBox gbox = new GroupBox();
                gbox.Name = name + i;
                gbox.Text=name+i;
                gbox.Width = 300;
                gbox.Height = 100;
                gbox.Location = new Point(32, 20 + i * 150);
                this.Controls.Add(gbox);
                //调用添加文本控件的方法
                AddTxt(gbox);
            }
        }
        //添加文本控件
        public void AddTxt(GroupBox gb) 
        {
            string name = "txt";
            for (int i = 0; i < 3; i++) 
            {
                TextBox txt = new TextBox();
                txt.Name =gb.Name+ name + i;
                txt.Text =gb.Name+"|"+ name + i;
                txt.Location = new Point(12, 15 + i * 30);
                gb.Controls.Add(txt);
            }
        }
    }
}
